Abstract: 

A new architecture of QDs has been designed using Carboranyl phosphinate ligands in water which shows a unique luminescence phenomenon called Kinetic Fluorescence Switching (KFS). It has never been reported before and was possible due to the spherical ligands. Further QDs have been synthesized which combines the advantage of organometallic synthesis and aqueous synthesis in one method using a new design set-up. Also, for the first time QRods and QRings have been synthesized in water and their luminescence properties were studied using photo or electric excitation.

Magnetic nanoparticles have also been used along with borane clusters to form new nano-hybrids which have been tested for Boron Neutron Capture Therapy (BNCT) for cancer treatment. In-vitro and In-vivo studies were done using these new nanohybrids. Also, new kind of magnetic nanocomposites were formed as part of the European Horizon 2020 project KARDIATOOL using MWCNTs, magnetic nanoparticles coated with silica and functionalized with different functional groups which were further rused to form non-bonded complex with H[COSAN] for sensing layers in biosensors.
